Vertical Ball Mills. When lime or water quality is poor and/or when lime consumption rates are high, STT designs slaking systems utilizing a vertical ball mill. The total grinding process of a vertical ball mill utilizes all residual reaction value, virtually eliminates grit disposal problems, and significantly improves lime usage efficiency.

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...
